(Cl. 99-236) The invention relates to a device in refining Figs. 3 and 4 show in vertical longitudinal secmachines for improving cocoa-containing masses, tion and in cross section the device in a refining such as preferably chocolateand cocoa-masses, machine having a drum rotating about a horizonwhich under continuous subdivision into very tal axis and a rotating blade mechanism with a large surfaces are subjected to the action of the horizontal shaft. 5 treating air, the working bodies being moved to Fig. 5 is an enlarged section of the roller I and fro or in circulation. Such machines are taken on the line V-V of Fig. 1 looking in the known per se.

.What I claim is:

1. In a machine of the character described, an.

aerating device, means for supplying a cocoacontaining mass to said aerating device in a predetermined direction, means for catching the aerated cocoa-containing mass and returning it to the supplying means, said aerating device comprising a hollow perforated distributing roller having its axis approximately normal to the direction of supply and provided with radial blades, a source of supply of aerating gas attached to said hollow roller, and means for rotating said aerating means. i V v 2.
